What is the function of pancreatic fluid in digestion?

The function of pancreatic fluid in digestion is primarily to contain digestive enzymes. The pancreas produces a variety of enzymes, including amylase, lipase, and proteases, which are critical in the breakdown of carbohydrates, fats, and proteins, respectively. When food enters the small intestine, pancreatic fluid is secreted into the duodenum, where these enzymes become active and play a key role in further digesting the food particles that have already been mechanically processed in the stomach.

Even though the pancreas also plays a role in hormone secretion, such as insulin and glucagon, this aspect pertains more to blood sugar regulation rather than digestion itself. Mechanical breakdown of food is primarily a function of the teeth and stomach rather than the pancreatic fluid. Nutrient absorption occurs mainly in the small intestine, not directly influenced by pancreatic fluid, which instead focuses on breaking down nutrients. Thus, the presence of digestive enzymes in pancreatic fluid is essential for the effective digestion of food in the small intestine.
